As events occur they are transmitted on the serial port. A rain event is transmitted as a time, and a
river event is transmitted as a time and river height. When an intelligent modem is connected to a
logger it is undesirable for this to occur, so events may be turned off by using the event flag. (Note
that when the event flag is off the power consumption will be improved, as the logger will wake up
for a shorter period of time when an event occurs)

When a logger is connected to an intelligent modem and the modem outputs a response that the
logger does not recognise, the logger will reply with "COMMAND ERROR" which may cause the
modem to respond etc....... This is undesirable, so the responses from the logger can be disabled by
turning off the response flag.

RE?
Response Output On/Off: En or dis "COMMAND ERROR" + ‘Going to sleep’
+ ‘Waking up’ responses to the comms port

When a logger dials out onto a communication network, there is no guarantee that it will be able to
successfully connect to the required destination (it may not be able to get a line or the line may be
busy) The logger will then wait 60 seconds and try again. The number of times it retries depends on
the RETRY variable.

RETRY?
Comms retry: Specifies the number of comms retries
should a comms call fail (60 sec between retries)
Syntax: RETRY<CR> Displays retry count
RETRY=3<CR> Sets retries to 3
